Suppose a hallway has a zig zag in it such that without the aid of mirrors you cannot see all the way down the hallway. In illustration below the mirrors are parallel to one another, and the dashed that appear to be parallel are in fact so. If one end of the mirror forms a 72° angle with the wall, then find the measure of x.

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 + 4x + 5 = 0

(x-5)1/2+5=2 what is a possible solution?
